This document specifies a test method for determining the comparative compression shear strength of adhesive bonds and solid wood at both ambient temperature and elevated temperature. The maximum load of the test pieces at ambient temperature and after exposure to a defined elevated temperature for a specified duration of time is evaluated. It is applicable to adhesives used in load bearing timber structures and to other wood adhesives. It is suitable for assessing the influence of elevated temperatures on the compression shear strength of the adhesive bond. This method is intended primarily to obtain performance data for the influence of elevated temperatures on the behaviour of adhesive bonds. It can be used for the assessment of adhesives for load bearing timber structures and as well for the assessment of non load-bearing wood adhesives with respect to their suitability for forming bonds in defined climatic environments@ at elevated temperatures. This method is not intended to provide data for structural design@ and does not necessarily represent the performance of the bonded member in service.
